Precision Turned/Ground parts

Good afternoon,

I am looking for someone, or a company that has the ability to produce precision turned and ground parts with high precision. this will include:

- ER collect cavities
- Cylindrical spindles with integrated ER collet cavities
- Cylindrical, ID, OD and thread grinding (not all at once)
- Ability to grind cones into the end of spindles (universal grinder?)

Tolerance would be ER ultra precision, T.I.R from 0.005 to 0.025 mm. OD and ID tolerances around the H7 but some into the J6 type of tolerance for holes, and g6/h7 ish for OD's/shafts.

Any one have any suggestions as to who we could try? or is anyone able to carry out this work.

If any one can help I would much appreciate it...

James
